Short video testing Sony RM-VPR1 remote control with the Sony Ax-53. Slow steady zoom out, zooming in slow and fast short bursts. This remote works with various Sony camera’s and can zoom, turn on/off camera, as well as take photos. Recorded at 4k 29 frames/second, audio 2 channels 197kbps @ 48 kHz with builtin microphone. Auto settings including active stabilization. My back yard, midday. Not a review nor endorsement.
